HENLEY, JOHN LALLY, JR., AND ELLEN T.LALLY, EXECUTOBS OF SAID JOHN LALLY, DECEASED, ASSIGNORS T LALLY COLUMN00., OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF MAS- sAoHUsETTs BEAMHANGER Application filed October 8, 1927. 'Serial No. 224,901.

My invention relates to beam hangers which are carried by I-beam headersand in turn carry wooden joists in building construction and it is myobject to produce a hanger which will be cheap, strong, light in weightand which will carry heavy loads without undue settling and which willbe solidly held in place so that it cannot shift and which avoids boringholes in the header. A further object is to so attach the bearing platethat it cannot become lost in transit and which plate will beself-levelling when the joist is placed on it.

In the drawing Fig. 1 is a side view, partly in section, of the hangeron an I-beam header and carrying a wooden joist; Fig. 2 a detail view ofa slight modification of the hanger; Fig. 3 a perspective view of thehanger of Fig. 1, Fig. 4 a view of the self-levelling bearingplate; andFig. 5 a top view of the hanger with the plate in position thereon.

, I As is usual in certain types of building construction an I-beamheader a and wooden mg. I

The hanger proper is preferably made of rolled, round stock and has abottom bar 1, which may be flattened to increase the hearing area incontact with a wooden oist, side bars? and 3 and top bars 4 and 5. Thetop bars are bent downwardly at 6 and 7 and are apertured, the upperedges of the apertures being approximately alined with the lower edge ofthe I-beam flange. I

In use the hangers are placed over the top flanges of an I-beam headerand wedges 8 are driven into apertures in the parts 6 and 7 therebylocking the hanger solidly to the I-beam. A hearing plate 9 may be laidon the bottom bar 1 and the wooden joist Z) is then dropped into place.Any tendency of the hanger to slide forwardly or tilt on the I-beam isresisted by the wedged top barswhich also resist any attempt of thehanger to work sidewise along the beam.

In Fig. 2 I have shown a slight modification in which the wedges and topbars are integral, thehook-like portion 10 being hammered or driven intolocking engagement with the beam flange after the hanger has beenpositioned,

and 2 extend on each side with the side bars passing through theapertures, the plate resting on the bottom bar. By this construction theplate can rock slightly on the bottom bar and be self-levelling underload while it is held in place on the hanger and cannot be separated andlost in transit. It also eliminatesthe expense of welding the plate tothe hanger.

By the use ofmy invention wooden joists may be used with I-beam headers.Heretofore it has been customary to use an ordinary Bethlehem beam withthe joists fitted between the flanges, but to get the necessaryclearances the I-beam had to be unduly heavy and expensive. By the useof my invention an I-bea1n of suitable weight and dimensions, such asthe recently developedJ ones & Laughlin sections, can be employed inplace of the previous expensive construction.

I claim":

1. Beam hanger construction comprising a hanger composed of a bottombar, sidebars and top bars, the ends of the top bars being bentdownwardly and perforated and adapted to lie over an I-beam header andwedges passing through the apertures and engaging the under side of thebeam flange.

2. Beam hanger construction comprising a hanger composed of a bottombar, side bars and top bars, the ends of the top bars being bentdownwardly and inwardly and adapted to lie over and engage the flange ofan IV-beam. and a bearing plate, apertured ears on said plate, the sidebars of the hanger passing through said plate apertures, the plateresting on the bottom" bar.

In testimony whereof I have aflixed my signature.

JOHN LALLY.
